Purpose: According to the metrological verification regulations of JJG536-2015 "Polarimeter and Polarimeter", a new measuring standard is required to verify the low transmittance indication error and repeatability of automatic polarimeter. Main parameters:
(1) Used in conjunction with standard polarizers that comply with OIML international recommendations (currently, standard polarizers produced by the Chinese Academy of Metrology meet the requirements)
(2) Low transmittance simulation values of 1% and 10%
(3) The relative deviation of the simulated value of 10% transmittance is better than ± 10%; The relative deviation of the simulated value of 1% transmittance is better than ± 20%.
(4) Power supply voltage: 220V AC
(5) High speed motor speed greater than 5000r/min
